Getting a magnetic field to balance on another magnetic field is about as easy as balancing a bowling ball on the tip of an ink pen. With a little help from an Arduino mega, however, [EmmaSong] was ...

The Arduino magnetic drawing machine operates using an Arduino board mounted with a magnetometer. This setup, combined with node.js and socket.io, allows the machine to detect disturbances in the ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

The project is based around the AS5040 chip that uses a magnet to provide positional feedback information and 10 bits of resolution per rotation. The project is based around the AS5040 chip that uses ...

“I looked at all the available rotary encoder sketches and none of them met my needs, so I have written my own, and here it is”. Well, I looked at all the available rotary encoder sketches and none of ...

austriamicrosystems has unveiled the AS540x product family of 3dimensional Hall encoders at electronica. The element has been designed to provide 'absolute and highest resolution' with angular or ...

Every week I seem to be writing about how someone has used an Arduino to fashion an interesting gadget, and today's – while not as obviously useful as, say a Pong-playing wristwatch - is still ...
